Graphics twitter, can anybody point me in the direction of generating the intersecting shape of two 2D shapes? I don't mean just detecting if two shapes intersect, but generating the intersection in the sense of constructive solid geometry.

What form are you looking to have the result in (is the result just visualization or data)? Are these convex polygons or curves?

I'm drawing the shapes on the gpu, so triangles. I currently don't have curves of any kind. polygonal shapes.

Can you just use the stencil buffer then with the increment operator to leverage the builtin rasterizer?

Unfortunately, I can't use stencil operations. I wish I could.
